Weather Forecast Feature
A special feature of the Watch is the
coming weather predicting function. It works by
analyzing the changes of the past air pressure.
How to Indicate the Coming Weather
The Watch provides 5 different symbols to
indicate the forecast weather, which includes:
- Sunny
- Cloudy with Sun
- Cloudy
- Raining
- Storm
The symbols will be shown only in Current Time
Mode and World Time Mode.
IMPORTANT: Since the Watch predicts the
coming weather by using the data of the changes
in the air pressure, it is highly recommended to
stay at the same altitude for at least 24 hours for
a higher accuracy predication.
IMPORTANT: The Watch predicts the weather
by adopting general weather prediction principles,
it is NOT capable to reflect the dramatic changing
of weather within a very short period of time.
Note: To allow storm prediction, see 7.1 to set
storm alert On/Off.

settings.
- When Storm alert is ON, 30 second beep alert
will be given and “ ” will shown in Current
and World time mode when the watch predicts
the upcoming weather is stormy.
- Before calibrate the sea level pressure, consult
the nearest observatory to get the sea and air
pressure of your current position.
Important: Storm alert is triggered when pressure
drops quickly with a certain period of time. But
sometimes, a very fast pressure changes maybe
due to altitude changes. This pressure changes
due to altitude variation may result in exactly the
same pattern as storm altert false alarm may
occur.
Note:
- Input an incorrect pressure during the
adjustment procedure may results an incorrect
pressure reading in the future.

What is Magnetic Declination
- The Magnetic North Pole which is slightly different from
the True North Pole. This Watch, like most magnetic
compass, points to the Magnetic North Pole, while
everything measure from a map is related to the True
North Pole.
- The angular difference between Magnetic North Pole
and True North Pole is called magnetic declination. Its
amount (degrees and minutes) and direction (easterly
and westerly) depend on where you are in the world.
- For serious compass user or whom intends to perform
accurate navigation, this Watch must be adjusted for
magnetic declination.
Magnetic Declination Information
- Most topographic maps include a small arrow which
shown magnetic north pole and or the magnetic
declination information.
- This manual includes the magnetic declination for some
major cities. See the coming chapter 'Magnetic
Declination at Major Cities' for more detail.
- For the cities are not included in the list, please refer to
the online magnetic declination calculator at:

Toggle the Daylight Saving Time (DST)
- Hold down the [L/R] button to toggle the daylight
saving time On/ Off.
- When Daylight Saving Time is On, one hour will be
adjusted (added) for this setting. About UTC (Coordinated Universal Time)
- Since the sun shines time on different places is different.
Therefore, our world is divided in to several time zones so that
people in different places can get a more accurate and
common time.
- All the time zone calculations are relative to coordinated
Universal Time (UTC). For example, the time zone of London is
‘UTC +0’. Los Angeles is 8 hours behind the time of UTC.
Therefore, Los Angeles’ time zone is ‘UTC-8’.

condition, the indicator will be disappeared when normal temperature returns.
- It is recommended to complete the battery replacement by a certified service agency, because this
Watch contains precise electronic sensors and components.
- The memory will be cleared if the battery has been replaced.
- See 8.4 to calibrate the compass before using the Compass again.
